RQTARY EGGFPRESERVER.

SPECIFICATION forming part of Letters Patent No. 271,658, dated February 6, 1283.

Application tiled April 21, 1882.

To all whom 'it may concern:

Beit known that I, ALBAR.P.RoBrNsoN,acitizen ofthe United States,residing at North Walpole, in the county of Cheshire and State of New Hampshire, have invented certain new v and useful Improvements in Rotary Egg-Pre- Eggs need i'or their preservation not onlyv whereby large numbers of them, While' being ltept cool, may also all have their positions changed at will as ol'ten as may be desired, to

prevent the contents ot' the shell from settling.

The invention consists in au apparatus, which l will now describe, and in certain details ot' its construction, theleadingfeatures being acooling receptacle or case tor holding the eggs properly, and adapted to he revolved or turned at willabout or with a horizontal axis, a mineral or chemical packing for such a revolving cooler or refrigerator, and a metallic lining iu part or in whole, which not only serves to keep the eggs dry and cool, but also for keeping or assisting' in keeping the mineral packing in place.

Figure 1 represents in perspective an apparatus embodying my invention and ready for use; Fig. 2, a transverse vertical section ofthe box or receptacle; Fig. 3, airagmentary transverse section ot' a side or top ofthe box; Figs. 4, 5, details; and Fig. 6, a modiiication showing the slats. f

A is the retrigeraiing case or box for holding the eggs, and which may bein any desired form, but preferably quadrangnlar in cross- (Model section; and it is provided with journals or axes b at each end, to permit it to be turned or revolved at will, these axes being adapted to rest in proper bearings in any proper snpport-a-s, for instance,in the frame orstand G such support having appropriate notches 0r cuts d for receiving the journals b,and having free space to permit the refrigerator or case to be revolved as needed from time to time. At one end ot` this case is made a series 'of depressions or shallow holes,e, arranged equallyv distant from the aXis,and in the corresponding end ot' the stand is made a hole,f, extending,r through it, and a peg or pin, g, is provided, which, being` put through the hole f and pushed into any one ot' the depressions e. serves to hold the case to any given position to which it may have been turned, and upon being Withdrawn and inserted into thel next or any other depression 6 securesit for the desired time in this changed position. In this way the incloscd eggs may be all inverted gradually or at once, or turned over to any degree desired.-

rlhe journals or arbors b may be secured to the ends of the boxin anysuitablemanner; but l prefer to make a. shoulder or ange on their inner ends, so that they may be held to place by a batteri or cleat, and on one ot1 these arbors i place a crank and handle similar to a. grindstoiie-c1'ank,br the purpose of turningor rotating the box.

The box may be of anv size or capacity required-say from two to four or even tel] feet long-and adapted for holdingor carryy ing from twenty-tive to a hundred and twenty-tive dozens, or even ten hundred dozens, of eggs.

The arbor may be made as shown in detail in Fig. 4.

For the purpose'ot providing space for and for holding the mineral or chemical packingin place between the exterior box, A, and its metallic interior lining, H, I use beveled slats i, arranged in the form ot' a frame, and secured against the inner walls and also against the 9 bottom and cover ofthe box, these bevels inclining, as shown, so that when the mineral or chemical paokingj shall have been filled into the space between these slats while in its moist or plastic condition it Will be, as it were,

ICO

dovetailed to its place; or, in other words, that face or surface of the packing which is against the wood or material composing the box will have a larger area than the other surface ot' this packing. This packing should be of a character colder than the egg-such, for instance, as plastcr-of-paris or sulphite of lime, cement, and sulphate of soda; or any other dis infecting mineral or chemical substance may be used for packing the rotating box and its lid or cover partially or entirely, which will preserve the proper temperature and moisture of the eggs. This packing, besides being cool and a preservative, is also a good non-conductor of heat, and the beveled slats keep it from cleaving off. I also, instead of the metallic lining or covering, sometimes use metal strips h to hold the mineral or chemical packing in place, and thereby leave such packing uncovered to a greater o'r less extent, and thus get the full benefit of the packing as a disinfectant for the eggs and preserve a more even and suitable temperature.

The linings H of the box and cover may be made of any desired sheet metal, preferably galvanized iron, and they may be secured, as shown, directly to the frame or slats t', thus not only covering, but also assisting to keep in its place the packingj and to prevent its Scaling or rubbing off.

For holding the eggs, socket-boxes or racks K may be used, placed one on top ofthe other, each space or compartment in these racks being adapted to hold one egg, and these racks may reach up to the top ofthe box; and to provide for the removal of any one or more of the racks from the box, and yet permit the proper rotary motion of the box without risk of damage to the eggs, a follower may be placed inside ofthe box, connected with ascrew extending up through the cover, and whereby this follower may be adjusted as needed to firmly hold the racks and eggs to place. Partitions may be placed, if desired, within the refrig erator-box.

The frame or stand Within or upon which the box is supported and turns may be lhorizontal instead of vertical, and such that any desired number of boxes may be hung in one frame,

My invention is adapted for the transportation of eggs, and these boxes or refrigerators may be placed on railway-cars. In such cases,

for the purpose of overcoming as far as practicable the shaking and jarring, rubber or spiral springs may be placed under the arbors of the box.

Tissue-paper may be used to advantage for wrapping the eggs before placing them in the box.

Each socket-box has not only the crossing partitions, but also a bottom attached to it, which not only separates the eggs of one layer from those of the next, but is also ot' a size such as to prevent the eggs or the layer of eggs from shifting endwise or sidewise of the box, and it also acts as a good non-conductor from one layer to another, and permits the ready lifting out at once ot' all the eggs in a given box.

Then each layer of eggs is placed in the box the vacant spaces are filled in with appropriate dry iilling material, such as corn-dust, shives from XVe-stern corn, rice-hulls," buckwheat hulls or chaff, cork-turnings, oat-chaff, &c.and which should be free from oil and not likely to throw'of an odor. The great essential is the adaptation for readily changing the position of the ent-ire body of eggs, while at the same time keeping them cool.

I claim- 1. The described rotatable egg-preserver, having the interior cooling mineral packing, having interior means for holding each egg separately and firmly during a complete stepby-step revolution ofthe box, and having journals and a frame with journal-supports to permit complete revolutions, and devices for holding the box at any successive stated points of such revolution, substantially as set forth.

2. A rotatable egg-preservingair-tight box, hung on centers which are substantially in a horizontal line, and adapted to be turned thereon and held stepV by step during its complete revolution inv vertical planes, to invertthe egg partially at cach step, and having a thick cooling or disinfectant mineral lining over the whole inside of the box, such lining being surfaced in whole or in part with metal, as shown and described.
